Adding players

If calling player has EditPlayerDB permission, they can add new names to the database (names of players who have never joined before). You will be asked to confirm. This may be useful for preemptively banning players. For example, to ban account "Notch" (who presumably never joined your server before) do:

/Rank Notch guest
/Ban Notch

Customizing /Rank behavior

Ability to promote/demote can be limited per-rank. By default, players with Promote permission may only rank players up to their own rank or lower. Players with Demote permission may only demote players of their own rank of lower.
